3 findings on this tool

  1. highexcessive agencyf-r4-tavily_map

    Tool `tavily_map` accepts an unbounded monetary / quota value

    The numeric parameter(s) `limit` have a money/quota-shaped name but no `maximum` constraint. An LLM tricked by indirect-injection can call the tool with arbitrarily large values.

    fix: Add a `maximum` (and ideally `minimum`) to each money/quota numeric, OR enforce the cap via a capframe-bind `--limit` caveat at the agent boundary.

  2. highssrf surfacef-r8-tavily_map

    Tool `tavily_map` accepts an unconstrained URL / endpoint parameter

    The parameter(s) `url` look like URL or endpoint inputs but carry no `pattern` or `enum` constraint. An agent tricked by an indirect-injection payload can invoke this tool with an internal-service URL (e.g. `http://169.254.169.254/`) to exfiltrate cloud metadata, probe internal APIs, or pivot to services the host can reach but the caller cannot.

    fix: Constrain the URL parameter with an allow-list `enum`, or a `pattern` that restricts scheme and domain. Validate server-side against an allow-list and reject private / loopback / link-local address ranges at the HTTP client level.

  3. mediumunconstrained inputf-r1-tavily_map

    Tool `tavily_map` accepts unconstrained string input

    The following string parameter(s) have no `maxLength` constraint: `instructions`, `url`. Unbounded strings let an attacker stuff arbitrary payloads through the tool, including indirect-injection content.

    fix: Add a `maxLength` to each string property, or constrain with an `enum` or `pattern`. Most legitimate tool inputs fit under a few hundred bytes.
